Hello everyone!
A few weeks ago Chrome released a new update including some new functionalities. They also introduced a new feature called “throttle expensive background timers”. The new "Background Tab Throttling" functionality limit the CPU usage of background tabs to 1% if they use excessive power.
Sadly, as a side effect it may freeze your game when it runs in the background and it only affects flash games / browser games!
Therefore we can’t fix the problem on our side but we can provide some useful hints to unfreeze your game in case this has happened:
Use the zoom-in function of the browser (in the normal browser menu or CTRL+ Mouse Wheel or CTRL+Plus)
Zoom out again (in the normal browser menu or CTRL+Mouse Wheel or CTRL+Minus)
The tab should be unfrozen now, if not you can try to resize the window by using the window mode.
If nothing helped try the following steps:
Note: For advanced users only!
Disable the flag in Chrome and Chrome-based Browser
Open Google Chrome and type chrome://flags in the address bar to open the advanced settings page!
Press “CTRL+F” and type “throttling” in the search box
Change the setting of the flag “Throttle expensive background timers” to “Disabled”
Relaunch your browser!

We hope these hints will help you to deal with this issue until Chrome gets an update to fix this issue.
